摘要: 为详细分析新疆某矿区的煤层露头情况,采用三维地震勘探方法进行煤层露头预测。利用先进的数字地震仪器设备采集野外资料,根据“高信噪比、高分辨率、高保真度”的原则进行了资料处理。根据煤层底板发育的反射波与新生界底界面不整合面的相交位置,并结合地震反演剖面进行煤层露头信息解译,解译结果得到了钻探结果的有效验证。研究表明:利用三维地震勘探技术在该矿区进行煤层露头预测具有可行性。

Abstract: In order to analyze the coal seam outcrop of some a mine area in Xinjiang,3D seismic exploration technique is used to forecast the coal seam outcrop.The field seismic data is acquired by using the advanced digital seismic equipment,the high-fold observation system is adopted to get field data with quality,based on the principle of "high signal to noise ratio,high resolution and high fidelity",the field high data is processed.According to the intersected position of unconformity between the reflection of coal floor and the bottom interface of Cenozoic,and combined with the seismic inversion section,the coal seam outcrop is predicted,and the prediction results is basically consistent with the drilling verification results.The study results indicated that is is feasible to prediction the coal seam outcrop by using 3D seismic exploration technique.
